To all @einem t may concern: i

"Be it known that I, HERMAN H. HELWIG, a "citizen of the United States,l residing` at Philadelphia, in the county ofiPhiladelph-ia andState of 'Pennsylvariim` have invented a new and useful Improvement in Buttons, of which the following is a specification.`

This invention relates to buttonsuof `the kind which are fastened to `a garment or other material by means of a` stud or the like which extends through the material and is secured to the body-portion of thebutton.

The objects of the invention are to pro duce a button Ofthis kind which is so con strueted as to greatly increase the strength thereof; also to produce a button Ofthis kind which is provided with means of improved construction for holding the stud inthe body portion of the buttonso that the stud can be repeatedly removed `without weakening the holding means; also to improve the conf struction of buttons of this kind in otherrespects hereinafter specified.

ln the accompanying drawings: Figure l, is a central sectional view drawn to an enlarged scale and illustratingfeatures ofthe invention. i

Figf, isa top or plan view with the front plate removed. y y y Fig. 3,"is a plan view of a spring plate for retaining the securing stud, and

The button shown inthe accompanying drawings includes `the usual rear shell A which is covered byineans of ay front plate or the likeB and which has a reduced rear or shouldered portion e in which the securing Or holding means for a stud C are secured, -the shell Aibeing .for this purpose provided with a hole al4 through Awhich the stud `is adapted to pass. The stud also is of the usual construction, and a shank portion `having a point c1 which is adapted to be forced through the material m, to which the butt-On is tol be secured and a screw-threaded portionic2 `which is adapted to `engage the studholding device. All of these parts may be of any usual or suitable construction and of themselves constitute no part` of this invention. i y f l Specification of Letters latent.`

Themeansfor holding the stud in place onthe body portion of the button include the usual. spring plate or disk D which is secured .in the rear portion e of the rear shell A of the button and which is slitted to forno two oppositely arranged "spring lips or fingers d (Z1, which extend from the outer portion): of `the plate or disk` toward ,the middle portiontliereof and have oppositely arranged. edges cl2 Z3 `between which the shank ofthe stud C is adapted to enter in such a manner that the Opposed edges of the spring lips will engage the screw-threaded portions ofthe shank of the stud. The spring lips or fingers are bent toward the front of the button so as to permit the shank of the stud. to be forced inwardly in a direction lengthwise of the stud between the opposed edges of the spring lips, causingthe spring lips to be bent forwardly by the shank of the stud and preventing the with* dra y*algof the stud.` ln order to remove the stud fr om the body portion of the button, the stud is turned so as to uuserew the shank `portion thereofI from engagement with the spring' lingers; The opposing edges of the spring lips or lingers` are preferably rectilinear', asshown in the drawings, and are not provided with indentations `or recesses into which the shank portion of the stud enters, as has been done in spring holding plates as l `Patent-ea Aug. 1v, 192e.

heretofore made. The rectilinear edges have been found to beimore effecti ve in gripping the screw threaded shank of the stud and greatly increase the life of buttons of this kind since the stud can be `repeatedly re moved `.from its operative position in the g button and `reinserted without decreasing the gripping action of the spring lips.

' The spring `plates are preferably reinforced by an annular metal washer Ewhich is secured to the shell A of the button in front of the spring plate D. The washer reinforces the spring lips so that the life of the button is greatly increased by adding the washer. The washer 1nay,\howe\i'er, be omitted. i f

The spring plate D andthe washer E, if the same is used, are made of such a diameter as to fit Within the reducedrear portion (L of the shell A of the button `and are held in place therein by forming an annular groove cry thereoi"V but also Vstrong button is produced by structure. The bead has the advantage that having I a shouldered in theV reduced rear portion a, this groove indenting the metal to form a holding ridge or Vbead F which securely holds the spring Aplate andy washer in their operative positions. The ridge or`bead F not only forms a secure holding means for the spring plate by engaging the same throughout` the periph- .does not in any way weaken the shellot' the button, so vthat a very means of this the/groove forms good holding means for the edges oa button hole with which the button is Vto coperate.A The holding bead F Vmakes' it possible to'produce a buttonxvhich is-liatte'r the button extends outwardly from the garment to a less extent.

`I claim as my invention:

l.V Ina` button, the combination of a shell rear portion, a `stud adapted to be Yinserted into said shell, a holding device for said stud arranged in saidshell,inengagement lwith said shouldered portion', andan annular bead formed in said shell by means o which the holding device is held in vplace against said shouldereldportion.

2. In a button, the combination of a shell havingA a shouldered portion, a `stud adapted to be inserted into said shell, a substantially circular plate 'in-V said shell againstl said shouldered portiony Vand provided with means for engaging said stud, and an annular-bead'formed in said shell and extending into the-same and engaging said circular plate for holding the plate in said shell and against said shouldered portion.

In a button, the combination oi a shell havingan annular rear portion of reduced diameter, a stud adapted to be inserted into said shell, a holding device for said stud Varranged in sai'dreduccd portion of the having substantiallyA shell, Vand an annular bead formed in the 'reduced portion'of saidV shell by means of which the Aholding devicevis vheld between said reduced portion and said bead.

'4. In a button, the combination with a shell and a: securing stud adapted to be inserted into said shell, of a holding plate arranged in said shell, said plate having a pair Aotoppositely arranged spring lips having substantially rectilinear edges adapted to engage said stud to hold the same against endwise movement out of said shell, and means for 'holding said plate in said shell. f

5. In a button,`the combination with a shell and a securing stud having a threaded shank portion adapted to Vbe inserted into saidvshell, of a holding device arranged in said she-ll including a pair of 'spring lips rectilinear 'opposed than those heretofore made, so that v edges between which the threaded portion ot said stud is adapted to enter and which hold the stud against movement endwise out of said shell, and means vtor securing said holding device in said shell.

6. In a button, the combination with a shell and a securing stud having a shank portion adapted to beY inserted into said shell, of a holding device arranged in said shell including a pair of spring lips having opposed edges between which the threaded portion of said stud is adapted to enter and which hold the stud against endwise movement out of said shell, a washer in said shell 1for reinforcing the outer parts of said holding deviceand means .tor securing said washer and holding device in said shell.
